About the Course What are Probabilistic Graphical Models?

Probabilistic Graphical Models

Uncertainty is unavoidable in real-world applications: we can almost never predict with certainty what will happen in the future, and even in the present and the past, many important aspects of the world are not observed with certainty. Probability theory gives us the basic foundation to model our beliefs about the different possible states of the world, and to update these beliefs as new evidence is obtained. 30 Days to Learn jQuery. streaming your code to the masses.

SSH tricks

As recently as a 2001, it was not uncommon to log in to a remote Unix system using telnet. Telnet is just above netcat in protocol sophistication, which means that passwords were sent in the clear. As wifi proliferated, telnet went from security nuissance to security disaster. As an undergrad, I remember running ethereal (now wireshark) in the school commons area, snagging about a dozen root passwords in an hour.

SSH, which encrypts and authenticates connections, had been in development since 1995, but it seemed to become adopted nearly universally and almost overnight around 2002. Backbone patterns. Here, I try to document the good practices that our team has learned along the way building Backbone applications.

Backbone patterns

Inline templates The problem: if you need to use view templates in a small Backbone application, defining your templates in JavaScript code will be unwieldy and difficult to maintain. Solution: You may need some view templates to be inline in the HTML page. This solution has been outlined by John Resig in his blog post about JavaScript micro templating.

Addyosmani/backbone-fundamentals - GitHub. Code School. Efficient JavaScript. By Mark 'Tarquin' Wilton-Jones Traditionally, a Web page would not contain much scripting, or at least, not much that would affect the performance of that Web page.

Efficient JavaScript

However, as Web pages become more like applications, the performance of scripts is having a bigger effect. With more and more applications being developed using Web technologies, improving the performance of scripts is becoming increasingly important. With a desktop application, a compiler is normally used to convert the source into the final binary. The compiler can take its time, and optimize as much as possible for good performance of the final application. Browsers are fairly good at achieving this, and Opera has one of the fastest scripting engines of any current browser.

This article will show several simple changes that can be made to improve the performance of your Web applications. Quick Tips ECMAScript Document loading.

Python is the best language in the world for interacting with the web, and I'm going to show you why. This article will give an extremely high level overview of how to use python for the web. There are many ways you can interact with the web using python, and this post will cover all of them. This includes python web scraping, interacting with APIs (Application Programming Interfaces) and running your own python web site using python server software. There are many ways to do all these things in python, but I'm going to show you how to do it the right way using the most modern techniques. Interacting with Websites and APIs Using Python The single best package for interacting with the web using Python is 'Requests' by Kenneth Reitz.

First, you'll need to install it. Once you have pip installed, run: pip install requests And now you have Requests installed! YUI3 « Triptych.

The Unix Command Line: Text Files. By Gordon Davisson Copyright (c) 2002, Westwind Computing inc. Working with Text Files: more and less - display the contents of a text file, one screenful at a time (hit the spacebar to get the next screen). Note that this only works well with plain text files, not Word files, RTF's, PDF's, or anything else that contains formatting information. less also allows you to go backwards (type "b") in the file.

I have long lost count of how many web sites I’ve built. You would think after having built a few hundred of them I would have discovered the “one true way” of doing it. I don’t think there is one true way. What I have discovered are techniques that can keep CSS more organized and more structured, leading to code that is easier to build and easier to maintain. I have been analyzing my process (and the process of those around me) and figuring out how best to structure code for projects on a larger scale.
